CVE-2020-2318: 
Java vulnerability analysis and mitigation

The Mail Commander Plugin for Jenkins-ci Plugin version 1.0.0 and earlier contains a security vulnerability identified as CVE-2020-2318. This vulnerability was disclosed on November 4, 2020, and affects the password storage mechanism in the plugin. The vulnerability is rated as Medium severity according to CVSS scoring system (Jenkins Advisory).

The vulnerability stems from the plugin's implementation of password storage, where passwords are stored unencrypted in job config.xml files on the Jenkins controller as part of its configuration. This represents a significant security weakness in the handling of sensitive credentials (Jenkins Advisory).

The impact of this vulnerability allows unauthorized access to stored passwords. Users with Item/Extended Read permission or those who have access to the Jenkins controller file system can view these unencrypted passwords, potentially compromising system security (Jenkins Advisory).

The vulnerability can be exploited by users who have either Item/Extended Read permission or access to the Jenkins controller file system. These users can directly view the unencrypted passwords stored in the job config.xml files (Jenkins Advisory).

As of the advisory's publication date on November 4, 2020, no fix was available for this vulnerability. The Jenkins security team has acknowledged the issue, but users must continue operating with the vulnerable version while maintaining strict access controls to the Jenkins controller file system and carefully managing Item/Extended Read permissions (Jenkins Advisory).
